The safest way to choose a sneaker size online is to measure both feet, use the exact brand and model’s chart, and check the size system on the listing. Your usual UK number is a starting point, not a guarantee across every sneaker.
Measure both feet
Use a flat surface, stand naturally and measure from heel to longest toe. Measure both feet with the socks you intend to wear and keep the larger measurement. If another person can help, it is easier to keep your weight balanced. Record the result in centimetres so you can compare it with the manufacturer’s chart.
Check the model as well as the brand
Jordan 1, Dunk, New Balance 9060, Onitsuka Mexico 66, Yeezy Slides and On Cloud are different designs. Do not publish or follow a single “always size up” rule for all of them. Check the official guidance for the precise model, including whether it uses unisex, men’s, women’s or children’s sizing. If the listing does not identify the scale clearly, ask support before ordering.
Understand a size conversion
UK, US and EU are labels, not measurements of the inside of the shoe. Foot-length charts and insole measurements describe different things. Use the manufacturer’s instructions rather than adding an arbitrary centimetre allowance or transferring another brand’s conversion table. Fit also depends on width, socks, shape and personal preference.
Try the pair without losing eligibility
Before wearing a delivered pair outdoors, check its labels against your order and inspect the fit on a clean indoor surface. Keep the original packaging and tags. If something is wrong, preserve photographs and contact support promptly. Read the order’s conditions before removing tags or using the product.
When a size exchange is available
Culture Circle is a marketplace: availability, price and delivery depend on the selected product and size. Check the estimate for your delivery location before paying. Eligible orders may support a size exchange; availability, verification, charges and request windows apply. Read size-exchange help, shipping information and the returns policy.
For authentication details, including CheckCheck eligibility and Brand Authenticity Certificate exceptions, see our authentication guide. A comparison article does not extend a product warranty or change an order’s terms.
A size exchange depends on an eligible replacement size, not just whether the original product remains listed. Review the quote for any price difference and processing charges before confirming.
